Um, the last book was called Nevermore. There are going to be no mais books but there is planned to be a movie and there are the mangá books. The movie was planned to come out in 2009 or 2010 but was delayed because they had to rewrite the script under cause of "there wasn't enough action". The latest delay was because they fired the directer and had to, once again, rewrite the script. It is unknown what the actors are. But on youtube there are fanmade trailers and my favorito Maximum Ride: Erasers and Max por MainstayPro.
